These photos show pictures of mature individuals. Young and baby cavies are not as easy to sex so the 'press test' is essential. I may be adding some pictures of young cavies to this page soon, so check back. Click here to go back to the sexing page.
 The typical i-shaped genitals of a male guinea pig. |
 The same boar with the penis extruded. Note that with this individual, we had to press directly over the genitals for it to work. Each cavy is an individual so you'll need to do some experimenting to find the right spot. |
 Another boar; note the large testicles obvious in intact adults. |
 The same boar with penis extruded. |
 The Y-shaped genitals of a typical female. |
 The same sow with fingers placed on either side of the genitals to gently pull them open. Note the bump near the anus; this is not usually as readily visible in males. |
 This sow has smoother, more rounded genitals. |
 The above sow with genitals opened. |
